+welcome BM.
I don't think f1 and d'pov will have an appreciation of the amount of debate (genuine debate, not point-scoring twatery) that's taken place on this forum about the uses and abuses of helmet-cams.
I use my cam as an insurance policy. Unlike maggers, I've not the drive to start a campaign. Unlike BM, I don't believe that posting bad driving on the interbob furthers the cause of cycling in the UK. This isn't because I have any moral queasiness about showing people at their very worst, rather I think it focuses a disproportionate amount of attention on the negatives. I could make a montage of the hundreds of people that give me enough room every day, but its not good television. You don't get a long take on "Police, Camera, Action" of plod chatting about the football while worrying a couple of cheese burgers. Also, youtube may be democratic, but its also filled with crazies. Life is too short to deal with "U R A SICELLING C***. GET OF OUR ROADZ" landing in your inbox every other day.
"You f****** hypocrit" some may say. And they'd be right. I do have a youtube account, and on it you'll find some more or less unpleasant moments. But if you check the dates, you'll find that these were posted in the first flush of excitement at owning a cam. I don't much bother these days.
Now I keep the account for two reasons - the first is that I still use it if I've had a run-in with a commerical vehicle. I post the vid, ring the company, get them to look at the vid and, if I'm happy with the response, I remove the vid. I've done this twice in two years, and twice the companies involved responded positively. I'm only looking for the small victories.
The second will be familiar to longer serving forumites (apologies for repetition - this is for the benefit of f1 and d'pov), but its an object lesson in why cyclists cam up, and why we are so concerned about the gap between our legal rights and the respect those rights are afforded.
Here it is. I walked away from this with relatively minor injuries (cuts, bruises, longer term damage to my shoulder, bike written off), probably thanks to my genetically big bones. This is great TV and I had my fifteen minutes, but the crash is the least interesting thing about it.
There were two witnesses who called the police and an ambulance immediately. The police turned up first, breathalysed the admitted shocked and contrite driver, checked his licence and let him go. Can you spot what's missing? He wasn't cautioned. What would he be cautioned for? Its a fender bender, right? The attending copper what nice enough, but as I wasn't dead or anything, what was the problem?
Now to the ambo driver. He was annoyed with me. What did I expect if I cycled, I was bound to get hit sometime. I wasn't wearing a helmet, so I deserved what I got. Funnily, what I didn't have was any head injuries. Despite sky-high blood pressure from shock, he effectively refused to take me to the hospital. Copper disappears to attend to some otherwise careful and law-abiding motorist who's just caused a multi-vehicle on the M3 and the ambo driver dumps me out on the street. I'm left to phone a colleague from work to pick me up and cart me home.
I could also talk about how his insurance company tried to accuse me of irresponsible cycling so that, without the footage and a solicitor handy in the black art of cycle claims, I'd still be fighting the claim now.
The police decided not to prosecute the driver for careless driving. These things happen. You can't blame the motorist.
